ATTORNEY Patented Jan. 5, 1937 UNITED STATES PATENT OFFICE PICKLING CRATE DEVICE Charles G. Watson, Austintown, Ohio Application August 31, 1935, Serial No. 38,764

2 Claims. (Cl. 266-7) This invention relates to pickling crates.

The principal object of this invention is to provide a pickling crate to be used in the conveying of metal sheets to and from a pickling vat and in immersing the sheets within the vat.

The purpose of this invention is the construction of a strong crate, yet one which is exceedingly light for the weight it is designed to carry.

A further object is to provide cross beams formed of a single sheet of metal.

A further object is to provide extended end portions welded to the upper edges of the side members of the crate.

A still further object is to provide triangular corner members for the purpose of bracing the crate and making it rigid.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein:-

Figure 1 is a top plan View of a crate.

Figure 2 is an enlarged detail View in perspective of a portion of the crate with parts broken away showing its form and construction.

By referring to the drawing it will be seen that there is provided a crate having a pair of oppositely disposed side frame members I. Between these frame members I there is positioned a plurality of cross beams 2 which are spaced apart and securely welded to the side beams I.

By referring to Figure 2 it will be seen that the cross beams 2 are each made of a single piece of metal by bending opposite edges at points 4 and 5, thereby forming a central vertical portion 3, and an upper portion 6 and a lower portion 1 which are spaced apart and opposite each other. It will also be seen that the upper portion 6 is slightly wider than the lower portion 1. Each of the upper portions 6 is provided with extended ends 8 which rest upon the upper edges 9 of the frame members I. In the construction of this crate these ends 8 are welded to the upper edges 9 of the frame member I and the end surfaces of the central vertical portion 3 and the lower portion 1 are welded to the inner surfaces of the frame members I.

By referring to Figure 1 it will be seen that there is provided two pair of oppositely disposed lugs H on the frame members I for the purpose of attaching eye bars for lifting.

There is also provided a spacer member l2 so that sheets of metal placed upon their edges will rest in notches in the spacer member in order to keep the surface of the sheets separated. The cross beams 2 are provided with a plurality of openings l3 for the reception of spikes I4 which support the sheets carried upon the crate. In order to hold the spacer member l2 in position there is provided a pair of oppositely disposed upright supports I5.

In order to construct a pickling crate that will carry the heavy load it is subjected to, there is provided reinforcing triangular corner members l6 which are welded to the side members I and to the end beams 2.

In the construction of the crate the beams are placed so that the upper and lower portions 6 and I extend outwardly from the center of the crate.

It is understood that the pickling crate above described may be made of any suitable material but is preferably made of Monel metal.

What I claim is:-

1. In a pickling crate, a pair of oppositely disposed side frame members, a plurality of cross beams spaced apart between said frame members, said cross beams formed of a single sheet of metal having a central vertical portion and parallel upper and lower portions, extended ends on said upper portions welded to upper edges of said frame members, ends of said lower portions and said central vertical portions welded to inner surfaces of said frame member, oppositely disposed lugs on said frame members to provide lifting means, substantially as described for the purpose set forth.

2. In a pickling crate, a pair of oppositely disposed side frame members, a plurality of cross beams spaced apart between said frame members, said cross beams formed of a single sheet of metal having a central vertical portion and parallel upper and lower portions, extended ends on said upper portions welded to upper edges of said frame members, ends of said lower portions and said central vertical portions welded to inner surfaces of said frame member, oppositely disposed lugs on said frame members to provide lifting means, a spacer member having notches for the purpose of holding sheets of metal apart, a plurality of openings in said cross beams, a plurality of spikes in said openings for supporting said metal sheets, oppositely disposed upright supports for holding said spacer member in position, reinforcing corner members welded to said side frame membersand to end beams, substantially as described for the purpose set forth.
